Answer:
b
Step-by-step explanation:
(x√7-3√8)(x√7-3√8)= (x√7)²-2*x√7*3√8+(3√8)²=7x²- 6x*2*√14+72=
=7x²- 12x*√14+72
Answer:
[0,infinity)
Step-by-step explanation:
Since it's a modulus function, f(x) will have a range of [0,infinity). Use desmos for graphing it
That depends on the shape of the triangle.
A scalene triangle has no lines of symmetry.
An isosceles triangle has one line of symmetry.
An equilateral triangle has three lines of symmetry.
If my hunch is correct, Watson, there is no triangle
with two and only two lines of symmetry.
